What a print really costs — material, power, machine time, failed prints — and the price you should charge for it.
A print costs more than the plastic it uses. The calculator adds up five costs, then works the selling price back from your platform fee and the margin you want to keep.
Model volume × material density × price per kilogram. A 42 cm³ part in PLA weighs about 52 g.
Average power draw × print hours × what you pay per kWh. Use the printer’s average while printing, not the peak on the power supply label.
Print hours × an hourly rate that pays back the printer, nozzles, belts and build plates over their working life.
Your failure rate applied to material, power and machine time — the cost of warped corners and first layers that didn’t stick.
Removing supports, sanding, washing and curing — minutes of hands-on work at your labor rate.
Both are taken out of the selling price, not added to the cost — which is why the price is worked backwards instead of marked up.
